TRANSFER APPARATUS.

Application led October 1, 1921. Serial No. 4,820.

To all whom. t may concern.'

Be it known that l, JOHN J. HAZLnwooD, a citizen of the United States,residing at Pittsburgh. in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inTransfer Apparatus; and 1 do hereby declare the following uo be a` full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to transfer apparatus of general application.

An aim is to provide a construction which is an improvement on, simplerand more efficient than that set forth in Letters Patent of UnitedStates #1,398,188 issued to me on November 21, 1921.

The invention resides in the construction attaining the various novelfunctions, combinations and advantages which are hereinafter set forthrelative to accompanying drawings of one practical embodiment.

In said drawings Figure 1 is a plan view of the improved apparatus.

Figure 2 is a view of the apparatus, partly in side elevation, andpartly in vertir-al section, and

Figure 3 is a rear elevation of the apparatus. y

Referring specifically to the drawings, wherein like referencecharacters designate like or similar parts, the invention will bedescribed by way of example, in connection with rolls A., which arerotatably mounted, and adapted to have material passing Jtherethroughtransferred therefrom. The invention of course is not limited to suchuse, but on the other hand is of general application, and maybe used forinstance not only in connection with rolling mills, but in ship yards inconnection with railroads, the removal of wreckage, and otherwise.

On a suitable foundation 4, the track rails may be laid for the travelof suitable rollingstock thereon. This rolling stock may consist of aplurality of substantially rectangular skeleton frames 6 to the ends ofwhich, as by means of bolts 7 bearing frames 9 are secured. Shortcoupling beams 10 are removably attached to bearings 9 as by means ofbolts 11. Brackets 12 secured to the under surfaces of the bearingframes 9 journal shafts 13 on which wheels -14 are keyed and whichtravel directly on the rails Bearing brackets 15 secured upon the upperends of the bearing frames 9 journal shafts 16 to which cranks 17 arerigidly connected and which journel shafts 18 eX- tending from a table19, of any desired construction and adapted for disposition with itsupper surface in a mediate the rolls A as seen in Figure 2.

Said rolling stock is adapted to be reciprocated relatively to the rollsA to move the table 19 toward and from` the'same and to this end, a linkor pitman 2O is pivoted at 22 to the rear frame 6 and at 23eccentrically to a rotatable disc 24 driven in any suitable manner asfrom a motor 25, to intermediate gearing within a casing 26 and a shaft27.

Crank levers 28 are keyed to the shaft 16 and disposed on the oppositesides to the bearing frames 9 to cranks 17. At each end of each lever38a roller 29 is provided, being mounted and rotatable on horizontallydisposed studs 30.

Four uprights or standards 31 mounted upon the base '4 for cooperationwith the levers 28. Ribs or flanges 32eX- tend outwardly from plates 31and provide downwardly and rearwardly extending cam ways 34 open at bothends as at n35 and36. One of the flanges 32 as at 37 Aforms a stoporabutment for engagement with the rollers 29. Extending at an angley tothe ribs or anges 32 are ribs or anges 38 on the standards 31 whichprovides cam ways 39 open at both ends. The innermost'ianges 32 are cutaway at 40 to provide openings, which are normallyV closed by dogs 41,pivoted to the standards at 42 and adapted to 'remain inand seek theposition shown 'in Figure 2.

'i stop 43 is providedon the standard 31 for engagement by dogs 41 asthey swing to open position, to prevent their passing the are' rigidlyplane passing interl vertical. The outermost flanges 39 are cutaway attheir lower ends as at 44r and the openings provided are normally closedby dogs` 45, pivoted at 46 on the standards. Dogs 41 and 45 are normallymaintained in and urged to the position shown in Figure 2 by counterweights 4'? mounted on rods 48 extending from the dogs. Rods 48 atSuitable locations have openings 49 therein to facilitate the attachmentof a tripping hook or means to raise dogs 41 and 45. Handles 59 areprovided for the manipulation of the dogs 41 andv45.

In operation, the motor 25 rotates the disc l24 in a, clockwisedirection and hence ptman 20 moves the rolling stock and the table 19awayA from the rolls with Wheels 1e traveling upon the tracks 5 as willbe understood. During such movement away from the rolls A, thelovvermost rollers 297 since the standards 31 are stationary, willtravel in the camivays 39. thus rocking levers 28, shafts 16 and cranks17. shafts 18 and accordingly the table 19 so that the contents of thetable 19 may be removed in a higher or different plane. Further rotationof the disk 24.- causes the other rollers 29 to move in the cam WaysBel, resulting in lowering the shafts 18 and accordingly the table 19and restoring the table and the apparatus as a Whole to cooperativerelation with the rolls A, that is, to the position of Figure 2. Levers28 thus swing in the path of a complete circle from the axes of shafts1G. lVhen an unusually heavy load is being lowered and space is limited7the dogs L.l1 and 45 may be moved from over the openings 40 and le sothat the rollers 29 may pass therethrough.

Since changes in the details may be resorted to, the same are reserved.

What is claimed is 1. A transfer apparatus consisting of a transfermember, truclrframes, means to connect said frames, wheels for saidframes, means ou each frame supporting' said transfer member, and meansto operate the last mentioned means to move vthe transfer member.

2. A transfer apparatus consisting of a transfer member, truck frames.bearing frames on said truck frames, Wheels journaled on said truckframes., means mounted by said bearing frames toactuate the. transfermember, and abutment means associate( viththe last mentioned means.

8. A transfer apparatus consisting of a transfer member, cranksjournaled to said membeiushafts for said crank, bearings for saidshafts, actuating levers for said shaftsh cam means'assoc-iated withsaid levers.

4. A ,transfer apparatus consisting of a transfer member, rolling stock,bearing frames on said rolling stock.y shafts journailed on said bearingframes, cranks on said shaft to which the transfer member' is journaled,actuating levers on said shafts, and stationary cam means to cooperatewith sain ctuating levers.

transfer apparatus consisting of a transfer member, rolling stock, apitman pivoted thereto, means to actuate the pitman, said rolling stockconsisting of truck frames, means connecting the frames on said truckframes7 axles journaled on said bearframes. Wheels on said axles,shafts, bearing members for said shaft on said bearing frames3 cranks.on said shafts journaled expose the openings by engagement withsaidactuating means.

8. In a device of the class deseribed having ribs providing a eamway.said Wav being open at lopposite ends, `one of said ribs having` anopening therethrough, second ribs providing a c-amway in communicationvvith said eamWa-y and disposed at an angle thereto, one of the secondribs having an opening, closures for said openings, operating means topass through said eamways, and means to permit movement of said closuresto uncover the openings.

In testimony whereof I affix my signature in presence of two Witnesses.
